Have a look at Paragraphs 11 to 13 to find out the comparisons made between people who live with oth
ers and those who live alone. Then fill out the chart below.

Paras. 11-13

If you live with other people, their temporary absence can be refreshing. Solitude will end on Thursday. If today I use a singular personal pronoun to refer to myself, next week I will use the plural form. While the others are absent you can stretch out your soul until it fills up the whole room, and use your freedom, coming and going as you please without apology, staying up late to read, soaking in the bath, eating a whole pint of ice cream at one sitting, moving at your own pace. Those absent will be back. Their waterproof winter coats are in the closet and the dog keeps watching for them at the window. But when you live alone, the temporary absence of your friends and acquaintances leaves a vacuum; they may never come back.

The condition of loneliness rises and falls, but the need to talk goes on forever. It's more basic than needing to listen. Oh, we all have friends we can tell important things to, people we can call to say we lost our job or fell on a slippery floor and broke our arm. It's the daily succession of small complaints and observations and opinions that backs up and chokes us. We can't really call a friend to say we got a parcel from our sister, or it's getting dark earlier now, or we don't trust that new Supreme Court justice.

Scientific surveys show that we who live alone talk at length to ourselves and our pets and the television. We ask the cat whether we should wear the blue suit or the yellow dress. We ask the parrot if we should prepare steak, or noodles, for dinner. We argue with ourselves over who is the greater sportsman: that figure skater or this skier. There's nothing wrong with this. It's good for us, and a lot less embarrassing than the woman in front of us in line at the market who's telling the cashier that her niece Melissa may be coming to visit on Saturday, and Melissa is very fond of hot chocolate, which is why she bought the powdered hot chocolate mix, though she never drinks it herself.

If you live with other people, ________________________. (Para. 11)

When you live alone: ________________________. (Para. 11)

Supporting details: We need to talk to others. ________________________. (Para. 12)

Supporting details: People who live alone will behave ridiculously: ________________________. (Para. 13)

根据下面内容,回答题: Twelve years ago, oceanographer Captain Charles Moore was skippering

根据下面内容,回答题:

Twelve years ago, oceanographer Captain Charles Moore was skippering his yacht the Alguita in the North Pacific. He sailed into a mass of floating plastic rubbish which took him and his crew a week to cross. This floating rubbish dump is now called the Great Pacific Garbage Patch and doubles the size of the USA.

The United Nations says there are now 18,000 pieces of plastic in every square kilometre of sea everywhere in the world. A walk along any beach will give you some idea of the seriousness of plastic pollution.

The trouble is, when we throw out plastic with the trash, the plastic doesn"t go away. Plastic does not biodegrade. It photo degrades into smaller and smaller particles which then enter the food chain.

Plastics contain cancer-causing chemicals along the food chain in increasing concentrations and end up in our fish and chips, along with hormone disruptors. Scientists try to tell us that we are killing ourselves as well as other animals. At least 200 species are, as I speak, being killed by plastic.

Whales, dolphins, turtles and albatross confuse floating plastic, especially shopping bags and six pack rings, with jellyfish.

Some countries have rebelled and banned plastic bags. And the first was brave Bangladesh. Then China took the same decision. Botswana, Canada, Israel, Kenya, Rwanda, Singapore and South Africa have also banned plastic bags. Notice how many of the world"s richest countries are not on this list. It"s an absolute disgrace.

Think globally, act locally. A small Australian town is now one step ahead of the rest of the world. The inhabitants of Bundanoon in New South Wales have banned plastic bottles from the town.

We need to follow their example and eliminate plastic from our lives, take care of the earth and vote for people we think will do the same.

The writer says that we can get an idea of how much plastic rubbish there is in the oceans by________. 查看材料

A.looking at the sea

B.travelling across the USA

C.sailing across the Pacific

D.taking a walk along any beach
